Streptococcus pyogenes strains associated with invasive and non-invasive infections present possible links with emm types and superantigens
Objective(s): Streptococcus pyogenes, a notorious human pathogen is responsible to cause a wide range of infections varies from superficial common clinical illness to severe and life threatening infections. To our knowledge this is the first report exploring the emm types and superantigen/exotoxin gene profile of S. pyogenes from Pakistan. Materials a...
متن کاملIdentification and Characterization of Novel Superantigens from Streptococcus pyogenes
Three novel streptococcal superantigen genes (spe-g, spe-h, and spe-j) were identified from the Streptococcus pyogenes M1 genomic database at the University of Oklahoma. A fourth novel gene (smez-2) was isolated from the S. pyogenes strain 2035, based on sequence homology to the streptococcal mitogenic exotoxin z (smez) gene. SMEZ-2, SPE-G, and SPE-J are most closely related to SMEZ and strepto...
متن کاملSusceptibility and emm type of Streptococcus pyogenes isolated from children with severe infection
Minimal inhibitory concentrations (MICs) and minimal bactericidal concentrations (MBCs) of various antimicrobial agents were measured against 12 strains of Streptococcus pyogenes isolated from children with invasive infections between 2003 and 2012. The patients ranged in age from 1 day to 15 years, with patients younger than 5 years, including three neonates, accounting for a half of the patie...
متن کاملAntimicrobial susceptibility patterns, emm type distribution and genetic diversity of Streptococcus pyogenes recovered in Brazil
Streptococcus pyogenes is responsible for a variety of infectious diseases and immunological complications. In this study, 91 isolates of S. pyogenes recovered from oropharynx secretions were submitted to antimicrobial susceptibility testing, emm typing and pulsed-field gel electrophoresis (PFGE) analysis. All isolates were susceptible to ceftriaxone, levofloxacin, penicillin G and vancomycin. ...
متن کاملemm gene polymorphism among streptococcus pyogenes isolated from
dna sequencing is the most conclusive method for emm (m protein gene) typing of streptococcus pyogenes. this method is not a feasible approach in developing countries where streptococcal infection is widespread among adults and children. alternatively the pcr-rflp has the potential for rapid screening of different types of s. pyogenes. to document the emm type distribution of s. pyogenes in a g...
